STOP FOR JOURNAL-BOXES.

Patented-Sept. 11,1906.

To all whom, it may concern.-

'a citizen of the United States of America, residing at McKeesport, inthe county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Stops for Journal-Boxes, of which thefollowing is a'specification, reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements injournal-stops as used in journal-boxes for preventing the end thrusts ofaxles or shafts j ournaled in the boxes, also to receive the wear andtear of the axle or shaft within the boxes and protect the contentsthereof. 1

The invention aims to provide a novel form of j ournal-stop which willwear a considerable period of time and may be renewed in part withoutdis osing of the entire sto In this connection have devised a journastop particularly adapted to be used in connection with the journal-boxes of rollingstock, although the use of my improved journal-stop relative to a certain type of journalbox is arbitrary, myinventionnot residing in the location of the stop, but in the detailconstruction thereof, which will presently bedescribed and claimed.

Reference will now be had'to panying drawings, wherein like numerals ofreference designate correspondin parts throughout the several views, inWhio Figure his a vertical sectional view of a conventional form ofjournal-box equipped with my improved journal-stop. Fig. 2 is a plan ofthe journal-box with the lid thereof removed. Fig. 3 is'a verticallongitudinal sectinal view of the box. Fig. 4 is a horizontal-sectionalview taken on the line a: x of Fig. 3. Fig. 5 is a front elevation ofthe'box, illustrating my improved stop partly positioned therein. Fig. 6is a similar view illustrating a stop as seated and in proper positionrelative to said box. Fig. 7 is aperspective view, partly in section, ofmy improved journahstop; and Fig. 8 is a'central longitu-- dinalsectional view of a journal-stop, illustion. In [the accompanyingdrawings Ihave' trating a slightly-modified formof construcillustratedthe end of a conventional form ofaxle 1, having an axle-bearing 2, uponwhich the acco'mis mounted a conventional form of car-wheel 3. Thecontracted or spindle end 4 of the axle extendsinto a conventional formof 1ournal-box 5, which is supported by the framework 6 and is adaptedto support a frame 7, which rests upon springs 8 8, mounted upon the topof the journal-box 5. The journal-box is provided with awontractedopening 9, which is normally closed by a spring-pressed lid 10 and aplate 11. The side walls 12 12 of the journal-box adjacent to theopening 9 are provided with outwardly extending lugs 14 14 and 15 15,forming parallel slots 16 17. The lugs 15 areprovided withupwardly-extending ribs 18, forming sockets 19 between the lug 15 andthe rib 18 journal-stop 21, which is'clearly illustrated in Figs. 1, 5,to 7, inclusive. The stop consfs s ofa' strong and durable metallicfoundationplate 22, the ends of which are provided at the upper andlower edges with re'arwardlyextending-bearing or su porting legs 23 23.while thefoundationate 22 is provided with an axle bearing of Babbittmetal or the like material 254.

In order that the Babbitt metal or a similar metal may be secured to'thefoundationplate 22, I rovide the plate with outwardlyextending ugs 25,which are adapted to engage in the Babbitt metal 24 when the same ismolded upon. the foundation-plate 22, thereby providing an extra rip forthe Bab bitt metal besides the face 0 the foundationplate. In some.instances the foundationplate 22 may be provided with a plurality of oenin s 26, (see Fig.-8,) and when molding t e Ba bitt metal 24 upon thefoundationplate 22 the metal may descend into the openings 26 and inthis manner become fixed upon the foundation plate. Even with these twomethods of securing the Babb tt metal upon the foundation-plate it isobvious that other means may be devised for acco'mplishing the samepurpose. not care to confine myself to the manner of uniting the Babbittmetal with the foundation-plate. The formation of the Babbitt ThereforeI do metal 24 upon the foundation-plate 22 is substantially rectangularin plan, and I provide the upper and lower edges of the Babbitt metalwith enlargements 24 24 the object of which will presently be described.

After the ournal-bearing 27 has been placed in the journal-box upon thecontracted or spindle end 4 of the axle ad the jourproved journal-stopis mounted in the journal-box to bear against the end of the contractedend or spindle 4 of the axle. In Fig. 5 of the drawings I haveillustrated the position of the stop within the journal-box be fore itis seated, this position of the journal-.

stop being assumed when the stop is moved The bearing or supportingtoward the axle. legs 23 of the stop pass within the'slots 16 and 17until the Babbitt metal 24 engages the end-of the journal-bearing 2-7and the axle 1, at which time it is forced downwardly, the legs 23 23riding within the verticallydisposed slots 20 until said legs engagebehind'the lugs 14 14 and Within the sockets 19 behind the lugs 15 15.tion, (see Fig. 6,) the Babbitt metal 24 is positioned between the ribs18 18 andin engagement with the end of the contracted or spindle end 4of the axle. The lugs 14 14 and 15 15 are adapted to prevent a rearwardWhen in this posimovement of the journal-stop, it being only possible toremove the journal-stop by ele-, vating the same until the legs 23 23register;

with the parallel slots 16 and 17; but whenf with this type ofjournal-box it is obvious d that it may be readily used in connectionthe stop is being used I- employ a key 29, which is mounted in anopening 30, forme in one of the side walls 12 of the j ournal-box, toengage upon the top of one of the legs 23 and prevent the ournal-stopfrom beingelevated until the key is removed.

Vfhen the journal-stop is in position Within g the journal-box, theformation of thelegs 23 23 relative to the foundation-plate -22 forms;

a transverse bridge structure or supporting the Babbitt metal, and asthis metal receives the wear and tear from the axle occasioned; byendthrusts a certain resiliency main- 1 tained by the foundation-plate22 on account;

of its idge-like structure will to a certain{ extent permit of thefoundation-plate re-f ceding before breaking. a

By constructing the J manner above described the entiredestrucournal-stops in the 1 tion of the stops incurred by suddenthrusts or blows which they receive is entirely eliminated, and byprotecting the foundationplate with a softer material than the late I amenabled .to use the foundation-p ates a number of times by simplyrenewing the Babbitt metal which they carry. The enlargements 24 24" arerovided to insure a greater contacting s ace of the Babbitt metal withthe end of the shaft than if they were not used, said enlargementstending to I lugs.

brace the contracted or spindle end 4 of the 6 5 bearing 27.

An important advantage derived from my invention is its adaptability toany type of journal-box which is reinforced by the lugs nal-bearing key28 placed therein my -im-- 14 and 16, providing slots 16 and 17 on theside Walls of the box, whereby the journalstop can be properly supportedtherein. Throughout the description of the journalsto I havespecifically described the use of Ba bitt metal inconnection withthestop; but I desire it to be understood that brass, bronze, or thelike composition can be readily used. By the construction of my improvedjournal-stop, together with the box in which it is used, a largeend-bearing surface is rovided for an axle and the stop is not depen enton the action of the lid or journalliner, but may be removed or replacedwith ease and without elevating the car, it only being necessary tosever the cotter-pins employed-to lock the journal-stops in position andto prevent persons from tampering with the same.

In the drawings accompanying this a pli-' cation I haveillustrated aconventional orm of journal-box, the detail construction of which willbe familiar and ap arent to those skilled in the art of rolling-stocconstruction, and while I have herein illustrated and described the stopas being used in connection with the journal boxes and bearings forshafts.
